Fixed #32919 -- Optimized lexing & parsing of templates.

This optimizes:
- Lexer.create_token() by avoiding startswith() calls,
- Parser.parse() by re-using the token type enum's value,
- Parser.extend_nodelist() by removing unnecessary isinstance() check,
- some Node subclasses by removing the implicit "nodelist" from
  "child_nodelists",
- Variable.__init__() by avoiding startswith() calls.
